LID FOR MINERS LAMPS.

SPECIFICATION forming pm of Letters Patent No. 281,846, dated July 24, 1.883.'

Application filed March 19, 1883. (Model.)

part of this speciiication.

Our invention has for its obj ect to provide for an oil-tight lid7 for miners and other similar lamps-'one that will hold its place when shut, and not liable to out and become smooth or loose, and in consequence fall off when in use.

Figure 1 is a lamp of ordinary form with our improved lid. Fig. 2 is the lid.

a is the upper disk, which is of metal and a little larger than the top of the lamp. I) is the lower or bottom disk. It is of metal, and fits neatly but not tightly in the top of the lamp. c is a disk of cork, rubber, felt, or any exible material, and is placed between the metal disk, and extends enough outside the rim of the lower disk to iit the mouth of the lamp tightly and make a complete stopper that will be oil-tight. v

The middle disk is` held firmly in place by means of a rivet, d, passing through the center and riveted on the outsides of the metal disks.

In case the cork or iiexible disk should wear or become too small, it can be expanded by tightening the rivet. e is a hole in each 'metal disk, made opposite, through which the flexible disk may be punctured by a sharp instrument, which will admit the air and suffer but little, if any, oil to escape.

Instead of the disks being flat, the metal ones may be concave, in which case a ring of Ilexible material fitting on the outside of the convex parts ofthe disk and the rim, extending farenough to make a stopper, could be used instead of the entire disk of ilexible material.

rlhe lamp is made aring at the top or open ing, asshown, and the outer rim of the cork,

at the bottom, is beveled, and is larger at the top, so that when it is pushed down in the lamp it willfit tightly therein.

Having thus described our invention, what we claim, and desire to secure Letters Patent on, is this:

1. In a minerslamp or torch, the lamp having its top or opening made slightly flaring, in combination with the hinged lid and the supplemental lid or disk, said lid and disk being suitably held together, and having between them a packing of cork, and having holes therein opposite to each other, which communicate with a corresponding opening in the cork for the purpose of vent, substantially as set forth.

2. In a miners lamp or torch, the lamp having its top or opening made slightly Haring,

in combination with the hinged lid and the supplemental lid or disk, said lid and disk being suitably held together, and having between them a packing of cork, for the purpose described. p

In testimony that we claim the foregoing as our own we hereunto aiix our signatures in the presence of two witnesses. i JOHN B. DEEDS. WILLIAM MACK.
